The second Ironman race of the weekend, Ironman Taiwan, was perhaps the smallest race of the season with fewer than 500 competitors. It also has the lowest number of Kona slots on offer – 25 distributed through the age groups present. The race itself is one of the slower Ironman events, but this may in part reflect the size and variance of the field along with the conditions.

This year’s race trended slower than the previous two. It’s cumulative over all three disciplines, but most prominent on the run. The net effect is an overall distribution that’s 20-30 minutes slower than the historical results.

Noting that the first year of results mixes in DNS numbers with the DNFs (inflating swim and overall figures) this year’s race saw a high proportion of the field DNF. Percentages were up on both bike and run, but with the field size so low the impact of drop outs is amplified.

Age group medians are broadly slower this year, but we also see a lot more variation with the smaller age groups The impact of outliers is also amplified in a smaller field, enough to influence the medians a little.

The race draws a spread of athletes, primarily from the region. Japan and Taiwan take the majority of the slots on offer.

Tracking times for specific age group positions shows the impact of the reduction in numbers. There aren’t as many athletes in many of the age groups and times have dropped off considerably for later positions. As the field shrinks 50th place might move from being middle of the pack to back of pack. The front of the race, those taking the podium, hasn’t slowed as much.

Based on the results list I’ve estimated the slot allocation at Ironman Taiwan and from that the likely automatic qualification times for the race. The final allocation may vary and roll down would also influence these times. You can review more qualifying times on my Kona qualification page.

Finally, the top twenty in each age groups. Again, we see the variance from small groups of athletes. For the most part times are slower than average and often slower than last year’s race. This is less often the case at the very front of the race – there’s not so much change for first place. Overall though, this year’s race came out slower than before, perhaps a result of a thinning of the field.
